Singer Rita Ora may have 99 problems, but she wishes that the rumor that she slept with Jay-Z wasn't one.

The trouble started when Holly Hagan, the redheaded star of the British reality show Geordie Shore, tweeted about rumors that Jay-Z cheated on his wife Beyonce with the 22-year-old singer. Rita and Rob Kardashian broke up about a month ago.

"Apparently Beyonce is denying claims... But if I gt cheated on I'd also deny it #embarrassing," Holly wrote on Twitter before deleting the posts.

According to the Daily Mail, Rita quickly fired back at Holly on Twitter this week, denying that she has hooked up with Jay-Z, her former mentor. "I stayed silent on one bulls**t rumour but this one I have to speak," Rita wrote. 

"Neva eva will any1 includin a red head dum z listin attention seekin whore try talk s**t about me& my family holly wateva da f*k ur name is," Rita continued before deleting the tweets. Talk about harsh!

The fiery tweets didn't end there. Holly then responded to Rita, tweeting, "Oooopsy getting told off, don't shoot the messenger! Of course I'm only a Z-list why would anyone care what I say ;)"

This isn't the first time that incendiary tweets were directed at Rita about her love life. Last month, Rob wrote on Twitter that Rita had cheated on him with upwards of 20 guys, one of whom is reportedly actor Jonah Hill

Apparently, even celebrities can feel like they've got a hard-knock life at times.
